The Jabber Object Access Protocol (JOAP) allows object attributes and methods to be accessed over the Jabber network. joap-perl implements JOAP in Perl. It lets developers define their own JOAP servers and classes in Perl, and it also lets them use remote servers and classes in a transparent and Perlish way.
StatusNet is a microblogging platform. A StatusNet site is a lightweight social network that helps a community, company, or group to exchange short messages, files, and data over the Web. Users can choose which people to "follow" and receive only their friends' or colleagues' status messages. It provides a service that is similar to Twitter, Yammer, SocialCast, or Salesforce.com Chatter.
Gauche is the Scheme I always wanted
I've been looking for a solid, high-performance Scheme implementation for general scripting and systems programming for several years now. I was really happy to find Gauche. It has an extensive library of support functions and binary extensions and great support for SRFIs (Scheme Requests for Implementation -- the "open standards" of the Scheme world).
Most "modern" scripting issues -- networking, XML parsing, text manipulation, Web programming, embedding and extending -- are nicely handled with clean interfaces.
I think that programmers who are looking for top-notch alternative to Python and Perl -- the crowd that is moving to e.g. Ruby and Groovy -- should take a close look at Gauche as a real alternative.
